Discussions about the Bose S1 Pro system

Bose S1 Pro

Designed for musicians, DJs and general PA use, the S1 Pro is the ultimate all-in-one PA, floor monitor and practice amplifier that's ready to be your go-anywhere Bluetooth music system for nearly any occasion. 

This is the place to discuss the S1 Pro system.

UPDATE on Post-Fix battery status:

Dec 23, at 100 percent.

Dec 29, at 80 percent.

Jan 1, at 70 percent.

Jan 4, at 60 percent.

Jan 6, at 50 percent.

Jan 8, at 40 percent.

Jan 10, at 30 percent.

(Approx. 70 percent drainage after 18 days. Losing an average of 5 percent a day since Jan 1. At this rate it would run down from full charge to 5 percent or less in three weeks.)

Bose has asked me to return this unit (No. 1) so they can re-fix it.  Apparently, they used bad parts the first time around. I intend to return it but first...

I have two S1 Pros. My unit No. 2 was returned to me today -- "fixed". I plan to keep both my units for now and fully charge both tonight. I will then compare the battery drainage levels of both units with one another.  In this way I can determine if Unit No. 2 returned to me today is maintaining a battery charge better then the still faulty Unit No. 1.

I hope to be able to conduct this analysis for two weeks (at which point I may need to start using a unit for gigs). Hopefully by then I'll have some sense on where things stand and I will return the first unit for the follow-on repair.

I will keep you abreast of the result.

I wouldn't bother Eddie, they didn't fix mine 

So there you have it, how can both be true? Sam Spoons and I both outlined that these types of batteries, if/when fully discharging and remaining that way, over time, this is a problem that can result in damaged/degraded battery. Yet, I've seen several threads from ST about how it's perfectly fine for the battery discharge and this whole drain issue is really not that big of a deal, bc the the battery is still fine once you give it a full charge.  At least that's what I saw him say in the past. Has ST come to accept that the drain issue does possibly harm/degrade the battery? 

2nd, I'm about to send mine back for "repair", but I assume this is an exercise in futility, seeing as how the replies here lately indicate that "fixed" units aren't fixed at all, as they still have the problem.  Is Bose just trying to sweep this issue under the carpet? Hoping we eventually give up on a solution and just accept that we got a product with a flawed design/build?

I've just finished a long conversation with the UK customer service dept and they will be taking my S1 back for another go at a fix. I have had an assurance that should it not be successful they will honour the full refund offer my dealer has made (despite this going on for considerably longer than their 30 day return period). FWIW in the UK the warrantee is with the retailer not the manufacturer so I shall be informing the dealer tomorrow. 

Just bought 2 S1’s today but haven’t received them yet. I just finished reading this entire thread. Quite a read I must say.
I was looking at the S1’s two years ago but went with an Electro-Voice Evolve 50 which I still really like. I bought it to replace an L1 model 1 classic and 2 B-1’s which I can’t seem to get myself to sell. (Use them both for stereo fed off the EV50) The Bose is bright, crisp, and airy contrasted to the bass and mids from the EV.

I’m really looking forward to these lighter S1’s and wonder if the S1’s can be run on cord power while the batteries are removed, figuring I would store the batteries until the venue called for them.

I understand and agree that the batteries shouldn’t discharge when the power is off. I also wish they would tell us what the issue is or was. Bose makes good equipment, things happen. What could it hurt to disclose their fix. I believe it would help with customer confidence.

I’ve worked equitably with Bose for issues with repairs for the L1 and trust they’ll figure out and fix/compensate these issues with the S1’s. It sure seems like it’s been a while though.

When I get mine I’ll check the manufacture date, test the charge retention and post what I see.

Don, I usually use my L1B2 setup, but occasionally we (acoustic bass, 2 guitars, percussionist, all of whom sing...plus a T1 and/or a Soundcraft 8-channel board) use two S1s, and maybe another one as a monitor. I charge the S1s up the night before and have had no problem over the past two years, as they easily last through our normal three, 50-minute per set gigs. You mileage may vary! Good luck.

My S1 Pro battery drains in two weeks if not recharged. Not a big deal for me yet as I play where there is power. I guarantee though that this issue, not fixed, will cause those who play where power is not available to look elsewhere. I did play a couple of outdoor parties last summer, and rather than haul out a hundred foot extension cord, used a little, very quiet, 750 watt generator. The S1 sounds too good for me not to use, regardless of the battery, though I hope they figure it out. I suspect it is a battery issue.

 

I keep my S1s charged at all times in my studio where I also use them for practice.

Primarily on the "off" setting unless I've played a gig with them, then I put them on Quick Charge until the batteries are topped off...

I've done gigs on battery for over 5 hours continuous playing through the S1s (3 sets + hours of music via bluetooth) with some battery left over.

Use them plugged in, with the batteries.  It will keep the batteries topped off.  The only time there's a  problem is if you leave them unplugged for extended periods.

It is not a battery issue, if removed the batteries lose minimal charge until the 30 day sleep mode kicks* in and, effectively, shuts the system down. The issue us the SI Pro drawing excessive power in 'idle'** mode (the SI does not appear to have an 'off' mode).

The issue, as has been said, will not affect you unless you need to leave the S1 for a couple of weeks or longer between charging and using 'off grid'/

* Li-Ion systems typically have a 'self discharge' off less than 3% per month.

** What your computer would call 'sleep mode'

See above, it shouldn't matter as the 'sleep mode will kick in after 30 days and the battery should last for many months or even several years. Even if it didn't it would only lose 3% over the 30 days if outside the S1.

update WRT my S1 Pro, It fell to 80% yesterday, 10 days after being fully charged, before repair it still registered 100% after 14 days. It took only 5 days to fall from 90% to 80% so I'm not now concerned that I had not fully charged it before testing.

I will be returning it tomorrow to give Bose one last chance to fix it.

In response to how long ..... First I did a couple weeks with battery in. There was a noticeable drop. When I removed the battery and left it a couple weeks it was an insignificant drain. This is the same with all my lithium battery operated devices. (Snow blower, lawn mower, chain saw, etc.).

I'm pretty sure it isn't, most Li-Ion power devices do not draw significant current from their batteries when switched off, this should be especially so for electro-mechanical devices which need no power when unused. Electronic devices like phones, laptops and suchlike may need a very small current to maintain settings but as a single CR3032 can maintain this for many years in a desktop PC or keyboard workstation it should not be enough to have a noticeable effect on a large Li-Ion battery.

It has been two weeks (14 full days) now since I started tracking my two S1Pros, checking every two days for battery drainage.  

I have surprisingly good news to report -- and a possible a solution to the problem.

First off, after 14 days both my units show four blue flashes and 100 percent battery levels when measured via the app.

Best to my knowledge, I have experienced minimal to no loss of battery life.

Compare this result to before. I had either a dead battery after 14 days (prior to the fix), or only 50 percent battery life (after the initial fix).

This time I did one thing differently than before that may have contributed to the improved battery performance:

I installed the latest firmware (7.1.5) prior to the test.

I cannot guarantee that this is why I'm getting the improved performance, but it is the only thing I did differently. If you haven't installed this latest firmware, it may be well worth your effort to do so.

Meanwhile, I will continue testing the battery performances of my two units every two days for as long as I am able. At some point, I will need to use the system, but for the moment I can use my L1 compact for gigs if need be.

Again, I will keep you abreast of any changes if and when they occur.

Thanks Archtop Eddy for the info! I just sent my two S1 Pros in for the repair, it's great to hear of the improved performance...

It's better than my first one was but, similar to my second one when new (but see above), It still wasn't 'fixed' so I sent it for 'repair' after which it was worse losing 20% in 10 days. It is now back in Belgium for a second attempt at a fix.

Hi, Sam Spoons.

ST has said that the firmware update does not affect the battery drain issue.

Please see the highlighted section below.

Hi, MRDL.

Update: Not sure if any of you have gotten this firmware 7.1.5

Product Update for the S1 from the Bose app (on my iPhone).

ST: Wondering if this is related to the battery drainage?

The firmware version 7.1.5 release notes say:

  • Supports power-saving features
  • Optimizes battery performance
  • Enhanced security for Bluetooth connection

These changes to do not resolve the battery drain issue that we are discussing in this thread. As I mentioned in my post above, I should have more information about the repair process soon.

If you use the Bose Connect app, it will download the firmware update and notify you when it is ready to update your S1 Pro.  It's much faster if you use a computer to connect to the Bose site and do the update with a Bluetooth cable. Please see the link below for details.

Hi, Everybody.

The S1 Pro uses a lithium-ion battery. Individual battery performance will vary due to battery age, storage conditions, and the number of charge cycles.

Bose does not guarantee how long a lithium-ion battery will retain its charge. However, we expect a fully charged battery in a new S1 Pro system will last 30 days with the power switch in the “Standby” () position if the system is using Firmware 7.1.5[1] or later.

After 30 days of non-use, the battery will enter Sleep Mode. Bose recommends that you wake up[2] the battery and fully charge it at least once a year. If you leave it in Sleep Mode for longer than a year, the battery may completely discharge and become unusable.


  1. Bose recommends that you update your firmware to the latest version for the best performance. See S1 Pro Firmware Update for details.

  2. To wake up the battery from Sleep Mode, plug your S1 Pro into a power outlet and turn the power switch to the “On” () position. See S1 Pro Battery Sleep Mode for details.
